Fertility after treatment with HCG for undescended testes (author's tranls)

Klinische Wochenschrift

151 out of 212 adolescents having had been treated by human chorionic gonadotrophin (HCG) before puberty because of undescended testes, were re-examined 7 to 12 years later at an individual age of at least 17 years. In 121 of them a semen specimen for sperm counts could be obtained. In 10 patients, however, no ejaculate could be collected because of their hypogonadism. 78 of these 121 patients examined by sperm count had a sufficient testicular descensus after HCG treatment. In 43 adolescents HCG therapy failed, therefore subsequent orchidopexy was performed. A normal sperm count was seen in only 39 per cent of the 121 patients. After unilateral testicular maldescensus 18%, after bilateral maldescensus 43% of the patients had to be evaluated as prospectively infertile. Maier and Spann reported sperm counts below 10(6)/ml in 9 out of 17 patients with bilateral maldescensus who had been treated by surgery alone. In the present study, however, only 9 out of 35 individuals treated for bilateral maldescensus by HCG alone showed sperm counts below 10(6)/ml. Plasma LH and FSH concentrations were determined in 93 patients, 6 out of which showed hypergonadotrophic values of FSH and sperm counts below 10(7)/ml. Subsequently, 3 cases of K...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
